The message about BFS was first seen on magazine in Linux. Shortly afterwards, gg1 Android mobile Rom was changed to CM and began to use BFS as the scheduler of kernel in his beta version cyanogenmod, after the trial, we found that the speed of the mobile phone system was significantly faster. Sliding the screen on the left and right by hand is as smooth as rolling pages under opera, resulting in a lot of fingerprint printing on the screen. It has been a long time ago. It coincides with the offi

There is a mechanism in JSP that allows you to insert a tag similar to HTML in the JSP page. This article introduces the basic concepts and components of JSP custom tag, and how to develop and apply JSP custom tag.
What is tagUsing the HTML language, We can edit our webpage as follows:

2. Add the attribute description to the TLD file:
I. Introduce tags
In fact, we have used several tags in JSP, such as
The advantage of tag programming is flexibility + encapsulation.
Flexibility is embodied in attribute assignment and can be assigned any value. For example,
Encapsulation is embodied in the encapsulation of internal behavior. Because labels are imp
Taglib
Tags are defined and distributed in a structure called the tag library. A tag library is a set of metadata and classes:1. Tag Processor: Java class that implements the custom tag function.2. Tag additional information (TEI): provides edge information to JSP containers to confirm tag attributes and create variable classes.3. Tag library Descriptor (TLD): an XML document that describes a single tag and the attributes of the entire tag library.

2. Find specific classes to implement these custom behaviors
The first requirement-find a custom behavior that belongs to that tag library-is done by the prefix of the label directive (Taglib directive ' s Prefix), so elements that use the same prefix on the same page belong to this tag library. Each tag library defines a default prefix that is used in a document in a tag library or in a page to insert a custom label. So, you can use prefixes other than those such

The first required condition-Identify the tag library that a custom behavior belongs to-is completed by the Taglib Directive's Prefix attribute of the tag command, therefore, all elements with the same prefix on the same page belong to this tag library. Each tag library defines a default prefix, which is used to insert custom tags in the document or page of the tag library. Therefore, you can use prefixes such as jsp, jspx, java, servlet, sun, and sunw (they are all

We know that the multiplication of two n-digit integers, if the regularAlgorithmThe time complexity is O (n2 ). However, using the fast Fourier transformation, the time complexity can be reduced to O (n logn ).
Assume that we want to calculate the product of the following two n-digit numbers:

All the items with a higher degree of support than the minimum level are called frequency sets.
